Introduction toSuDSContinuing urban development, a changing climate and the consequences of increased rainfall are all increasingly prominent issues on the political and environmental agenda and all drive the need to actively manage excessive rainfall with the use of SuDS (Sustainable Drainage Systems).
SuDS techniques recommend a number of ways to control water run-off as near to where it falls, via:
Soft or natural SuDS Hard or engineered SuDS
SuDS should also aim to mimic nature, whilst focusing on 4 key areas (as shown below):1. Controlling run-off / flood risk2. Improving water quality3. Providing amenities 4. Creating an environment for biodiversity
The CIRIA SuDS Manual gives guidance on all areas of SuDS and focuses on the cost-effective planning, design, construction, operation and maintenance of SuDS.
Which SuDS Techniques are best?
SuDS should help maximise amenity and biodiversity, whilst also delivering key objectives to manage flood risk and water quality
For any given site, it is often beneficial to include a combination of ‘soft’ and ‘hard’ SuDS to ensure maximum efficiency from the Sustainable Drainage System
How can the Wavin help with SuDS projects?
Wavin is well qualified to advise on how to comply with current and emerging regulation. We can aid specifiers, developers and contractors in responding to legislative demands as they pertain to flooding, sewage, urban drainage and sustainable resources use.
In particular, the proven qualities and performance of AquaCell systems not only support the achievement of SuDS, they can also help reinforce and enhance planning applications and enable development to proceed.

Keeping you on top of legislationFlood and Water Management Act 2010
Climate projections suggest that extreme weather will happen more frequently in the future. The Flood and Water Management Act is designed to reduce the risk of flooding and its consequences by providing for better, more comprehensive and co-ordinated water management, embracing groundwater, surface water and coastal erosion risk.
The Act gives DEFRA responsibility for establishing national standards for sustainable drainage and empowers local authorities to manage local flood risk – adapting and maintaining sustainable drainage schemes.
Specifically with regards to stormwater, Building Regulations Approved Document H3 stipulates that adequate provision should be made for rainwater to be carried from the roof of a building to either a soakaway, water course or sewer.
The EU Water Framework Directive
Nearly half the EU population lives in ‘water-stressed’ countries, caused by high extraction from freshwater sources, and demand is growing all the time.
The EU Water Framework Directive introduces a new legislative approach designed to better manage and protect water resources, based not on national or political boundaries but on the natural formations of river basins.
Building Regulation Part H (Drainage and Waste Disposal)
Building Regulation Part H embraces the guidelines for drainage and waste disposal that must be met in the UK.
Although Part H extends to rainwater drainage and solid waste storage, waste drainage issues are to the fore. The Building Regulations are designed to ensure that all foul water (waste from urinals, portals, food preparation water etc.) is properly disposed of to maintain a decent level of sanitation, promoting both personal and environmental health.
The regulations also highlight the importance of pollution prevention, working sewage infrastructure and sewage maintenance.
Planning Policy
Statement 25: Development and Flood Risk Responding to climate change, and replacing Planning Policy Guidance Note 25, the statement PPS25 sets out policy to ensure that flood risk is taken into account at all stages of the planning process and that inappropriate development in areas at risk of flooding is avoided.
The policy directs development away from areas of highest risk and where new development is, exceptionally necessary in such areas, aims to make it safe without creating an increase in flood risk elsewhere and, where possible, reduce flood risk overall. Statement 3: Housing PPS3 underpins the delivery of the Government’s strategic housing policy objectives. The statement replaces Planning Policy Guidance 3: Housing and earlier editions of PPS3, providing technical amendments to Annex B: Definitions to reflect the introduction of Affordable Rent.

OverviewAquaCell SystemsThe AquaCell range of geocellular systems are a fully tried and tested, BBA approved, modular technique for managing excessive rainfall.
Applications
The AquaCell range can be used as either a temporary storage tank or as a soakaway, and is suitable for applications including:
Landscaped areas Parks Domestic gardens Residential developments Car parks & roads Industrial/commercial areas
The AquaCell Range
There are four types of AquaCell unit. Each can be used as a standalone system or different unit types can be mixed and matched together in layers to value engineer the most cost effective solution.
All AquaCell units have identical dimensions (1m x 0.5m x 0.4m), but they are manufactured to perform differently. The type of unit, or combination of units required will depend on factors such as the load application, overall installation depth and site conditions.
Features & benefits
The following are applicable to all AquaCell units: Fully BBA Approved – Eco/Prime/Core/Plus are all approved under certificate No. 03/4018
Modular, lightweight and versatile Easy to handle and quick to install Proven clip and peg connection system 95% void (each unit holds 190 litres of water) Can be brick-bonded for extra stability Units can be mixed and matched together for optimum performance
Safer than open or above ground storage structures Full range of ancillaries Can be used as part of a SuDS scheme to help reduce flood risk
Environmental Benefits
In addition, the AquaCell range can also offer the following environmental benefits:
Significantly reduced flooding risk Controlled, reduced-volume release of stormwater into existing sewer systems or watercourses
Recharging of local groundwater (if infiltration/soakaway application)
Aerobic purification to improve water run-off quality Sustainable, cost effective management of the water environment

Application
AquaCell Eco is manufactured from specially reformulated, recycled material and has been specifically designed for shallow, non-trafficked, landscaped applications. AquaCell Eco is NOT suitable for locations subject to high water tables.
AquaCell Eco is typically suitable for installations to a maximum depth of 1.5 metres, to the base of the units from ground level, with a minimum cover depth of 0.3 metres, (Wavin’s recommendation, is to allow a cover depth of 0.5 metres).
Any installation using AquaCell Eco must NOT be subjected to additional loading at any time. Trafficking by construction plant on site, including mechanical equipment, must be avoided.
If trafficking of the buried tank by construction plant or, other vehicles is unavoidable, the installation should be constructed using AquaCell Core units (see page 11).
The width of an AquaCell Eco installation should not exceed 12 metres to allow for mechanical backfilling without loading. There is no limit to the length of the installation.

AquaCell Plus: for inspectability
By aligning AquaCell Plus units end-to-end, full length viewing channels can be created – allowing for CCTV inspection if required. These are created in the bottom layer of an AquaCell tank installation.
The units can be used in combination with AquaCell Prime and Core (and with Eco if there is at least one layer of AquaCell Prime or Core in between the Plus and Eco layer).
NOTE: For any AquaCell Plus units on the perimeter of a structure that are NOT required for inspection access, the open ends of the integral inspection tunnels should be fitted with the end caps
provided.
Inspection chambers
An inspection chamber should precede the inlet pipework for the AquaCell structure.
A silt trap or hydro-dynamic separator prior to the inspection chamber is also recommended.
For on-line installations the following Chambers are recommended:— Down to 3m Wavin Non-Entry Inspection Chambers— Down to 5m Wavin Range 600 Inspection Chambers, or a
traditional manhole*
*where inlet pipework is replaced by AquaCell units acting as flow conduit.
For off-line installations:– Manhole with in-built flow control
Recommendation: If installing any Wavin Non-Entry Inspection Chamber, deeper than 1.2 metres, ensure that the cover and frame includes a 350mm restrictor to prevent man entry.
Inspection and maintenance
CCTV inspection at every inspection point is recommended:
— after every major storm — at regular intervals according to the specific maintenance
plan for the site
Silt traps prior to inlet pipework should be routinely inspected and cleaned out to minimise debris reaching the tank. It is important to prevent construction silt from entering the AquaCell structure.

Design GuidanceAquaCell UnitsInfiltration or attenuation?
The AquaCell range can be used either as:
A soakaway whereby the units will be installed in suitable pervious soils so the units can be wrapped in a geotextile to allow infiltration of the stormwater into the surrounding ground, or
As an attenuation tank in impervious ground (e.g. clay) where infiltration is not possible, here the units are encapsulated in a geomembrane (which is in turn wrapped in a protective geotextile layer) so that the structure can hold the stormwater temporarily until local drainage flows can accept it for normal disposal at a permissible outflow rate.
Site assessment
Ground conditions may be established as part of a geotechnical assessment. This may include tests for infiltration and ground water level.
If there is no confirmation that such assessments have been conducted, or resulting conclusions are unavailable, a trial pit will be required in accordance with BRE 365. For further information and guidance, please contact the Wavin Technical Design Team.
Infiltration (soakaways)
According to the principals of SuDS, wherever possible stormwater should be drained back into the ground via a soakaway as the first priority. A site must meet BOTH of the following criteria for infiltration to be possible:
The underlying soil surrounding the proposed installation is sufficiently permeable
The seasonally high water table is a minimum of 1 metre below the base of the proposed installation
If either of these criteria is not met, or cannot be confirmed for any reason, a soakaway system may not be suitable for the application, in which case a storage tank must be used.
Attenuation (Storage tanks)
A storage tank may be designed to be online or offline (see pages 28-33 for typical details). However, if the site is subject to groundwater or a high water table, it is important to ensure that the tank is not vulnerable to flotation. Sufficient weight from soil, or other covering placed over the AquaCell units, must be sufficient to counter any buoyancy uplift force from the rising groundwater level.

Important design considerations for geocellular structures
Rising rainfall levels and increased focus on SuDS compliance, have led to a sharp increase in the use of modular units to create underground structures for infiltration or the temporary storage of stormwater. However, not all currently available systems have the proven performance characteristics necessary to meet the wide range of complex underground geocellular applications. The Wavin range of AquaCell units provide assured performance, since all strength and hydraulic capabilities have been verified by independent testing and all units are fully BBA approved.
To guarantee the structural integrity of an engineered drainage system, any underground structure must be strong enough to support the loads to which it will be subjected without any unacceptable deflection. The correct choice of geocellular unit must have appropriate proven top (vertical) and side (lateral) load bearing capacity and deflection characteristics to suit site conditions.
The five key site considerations to be noted when designing a geocellular structure are:1. Depth of cover (See page 16)2. Soil type3. Surface finishing4. Presence of groundwater5. Type of traffic/loadingThe combination of these 5 factors effectively means that the
required characteristics of a geocellular structure to be installed under a trafficked location (for example) will be very different from that under a landscaped/low-loaded location. Two typical examples are given below.
EXAMPLE A: Landscaped/non-trafficked location and 0.3m cover depth. Typically requires minimum vertical strength of 17.5 tonnes/m2
EXAMPLE B: Car park with occasional light delivery traffic and between 0.71 – 0.75m cover depth. Typically requires minimum vertical strength of 40 tonnes/m2

Design GuidanceAquaCell UnitsHydraulic Design
All AquaCell units have identical dimensions: 1m x 0.4m x 0.5m, have a nominal void ratio of 95% and each holds 190 litres of water. Hydraulic calculations are accordingly the same for AquaCell Eco, Prime, Core and Plus.
Structural design however, requires careful consideration of loading factors specific to each location – see CIRIA C680 and CIRIA C737 for further guidance.
Structural Design – Installation & cover depths
Each AquaCell unit has been designed to have specific loading capacities (see pages 9-12) that define the maximum depth parameters for which they are suitable. Minimum depth of cover varies according to whether or not the installation will be subject to trafficking by cars/HGVs. However, in some situations, installations may have to be located with greater cover depths. Reasons may include:
Deep-running drainage network Other buried services running above tank location
Installation into banked/ sloping ground
Upper layer of clay preventing infiltration.
The table shows a summary of typical cover depths and installation depths as a guide.

(b) 0.3 is minimum depth for AquaCell Eco, although 0.5m cover is recommended to prevent accidental damage. If construction plant is to be used on site, extra protection may be needed.
(c) Allowable maximum depth to base of bottom layer of units is dependent on soil type, angle of shearing resistance, loadings, and groundwater level. The above depths are based on 38° angle of shearing resistance and no groundwater.
Typical minimum cover depths and maximum installation depths
The height of any tank should not exceed 2m (5 units). If you require a tank that exceeds this, please contact Wavin Technical Design for guidance:

Design GuidanceAquaCell UnitsMix and match
Although all AquaCell units have identical dimensions, and a high nominal void ratio of 95%, they are manufactured to perform at a range of depths, dependent on soil type, angle of shearing resistance, loading and ground water levels. For optimum performance the units can be mixed and matched (in layers) to value engineer the most effective design (in cost and performance terms) for each installation. For example, in a landscaped application if you needed to install a tank or soakaway that is deeper than 1.5m, you could install layers of AquaCell Prime underneath the AquaCell Eco. See below illustrations showing examples of how the AquaCell units can be mix and matched together. For advice on how to optimise a tank or soakaway design using more than one type of AquaCell please contact Wavin Technical Design.
Note: AquaCell Eco cannot be used directly with AquaCell Plus therefore there must be a layer of either AquaCell Prime or Core between them.
Typical examples of Mix & Match with AquaCell
Brick bonding – for extra stability
When assembling a geocellular structure that comprises two or more layers, it is recommended that AquaCell units are placed in a ‘brick-bonded’ configuration for extra stability.
This helps minimise continuous vertical joints in the assembly, and gives the structure extra stability.
A significant advantage of AquaCell unit design is that brick bonding placement does not require extra connectors.
All four AquaCell units may be placed in this way, unless inspection channels and cleaning access are required using AquaCell Plus.
AquaCell Plus units incorporate integral inspection channels. These are designed for combined alignment to create viewing tunnels at the base of an assembled structure (see page 13).

Installation GuidanceAquaCell UnitsAquaCell Prime, Core and Plus: Construction Loads
Construction plant such as excavators can impose significant loads on any AquaCell unit. The following guidelines should be observed:
Tracked excavators (not exceeding 21 tonnes weight) should be used to place fill over the AquaCell units when the geotextile or geomembrane wrapping has been completed
At least 300mm of fill should be placed before the excavators or trucks delivering the backfill are allowed to traffic over the installed units
Compaction plant used over the AquaCell units should not exceed 2300kg/metre width. This will allow the compaction of Type 1 sub-base in 150mm layers over the units in accordance with the Specification for Highways Works
All other construction plant should be prevented from trafficking over the system once it is installed and surfacing completed, unless a site specific assessment demonstrates that it is acceptable
In particular cranes should not be used over, or place their outriggers over the system
AquaCell Eco: Construction Loads
As AquaCell Eco is designed for landscaped and non-loaded applications, certain precautions are recommended on site to prevent damage to the units through excess loading.
Manual assembly
Whilst assembling the tank, it may be necessary to walk on top ofpreviously laid AquaCell units. Therefore care should be taken not to damage the edges of the units.
Backfilling
When backfilling AquaCell Eco installations: Machines placing the material must be located OFF the units Only light compaction should be applied to the material Backfill with suitable, stone-free, as-dug material First layer should be 300mm thick before using any compaction plant
NO vibratory mechanism should be used for compacting this first layer
Compaction plant must not exceed 2300kg per metre width
Construction traffic on site
Once backfilled, if construction plant (e.g. excavators or loaders) are likely to run over the installation, ensure that:
MINIMUM protective cover should be 500mm well-compacted granular material
Only tracked excavators can be used and MUST NOT weigh more than 14 tonnes.
HGVs MUST NOT run over installed AquaCell Eco units
Manual assembly
All ancillaries and adaptors (see pages 36-39) can be used with either the AquaCell Eco, Prime, Core or Plus units, except the 225mm Flange Adaptor (6LB106) which must only be used with AquaCell Prime, Core or Plus.
The 150mm Flange Adaptor (6LB104) should only be used whenconstructing an air vent on the top surface of an AquaCell Eco unit. The adaptor should not be used to connect inlet pipes to theside of an Eco unit.

InstallationAquaCell UnitsTypical Soakaway Installation Method
Typical installation procedure
1. Excavate the trench to the required depth ensuring that the plan area is slightly greater than that of the AquaCell units.
2. Lay 100mm bed of coarse sand or non angular granular material, level and compact.
3. Lay the geotextile* over the base and up the sides of the trench.
4. Lay the AquaCell units parallel with each other. In multiple layer applications, wherever possible, continuous vertical joints should be avoided. AquaCell units can be laid in a ‘brick bonded’ formation (i.e. to overlap the joints below) – see page 18. For single layer applications use the AquaCell Clips and for multi layers use the AquaCell Clips and the AquaCell Shear Connectors (vertical rods).
5. Fix the Adaptors to the AquaCell units as required and connect pipework.
6. In order to prevent silt from entering the tank, clogging inlet pipework and reducing storage capacity, it is recommended that the Domestic Silt Trap (6LB300) or the standard Silt Trap (6LB600) is installed prior to the inlet pipework – see page 26 for installation guidelines.
7. Wrap and overlap the geotextile covering the entire AquaCell structure.
8. Lay 100mm of coarse sand or non angular granular material between the trench walls and the AquaCell structure and compact.
9. Lay 100mm of coarse sand or non angular granular material over the geotextile and compact.
10. Backfill with suitable material.11. Rainwater from roof areas may discharge directly into the
soakaway but rainwater from carparks must discharge through a catchpit manhole and/or a petrol interceptor.

Example shows the use of AquaCell Eco. However, a soakaway can also be installed as shown using either of the other versions of AquaCell units (Prime, Core or Plus) as appropriate.
*The geotextile should be selected according to specific site conditions. Typically, however, a 300g non-woven material will be suitable. Specialist advice should be sought if surrounding soil characteristics exhibit a high degree of fines/low infiltration capacity and/or there is a high risk of damage from ground contaminants.

Typical Storage Tank Installation Method
Typical installation procedure
1. Excavate the trench to the required depth ensuring that the plan area is slightly greater than that of the AquaCell units.
2. Lay 100mm bed of coarse sand, level and compact.3. Lay the geotextile over the base and up the sides of
the trench.4. Lay the geomembrane on top of the geotextile over the base
and up the sides of the trench.5. Lay the AquaCell units parallel with each other. In multiple
layer applications, wherever possible, continuous vertical joints should be avoided. AquaCell units can be laid in a ‘brick bonded’ formation (i.e. to overlap the joints below) – see page 18. For single layer applications use the AquaCell Clips and for multi layers use the AquaCell Clips and the AquaCell Shear Connectors (vertical rods).
6. Wrap the geomembrane around the AquaCell structure and seal to manufacturers recommendations.*
7. If side connections into the AquaCell units is required, (other than the preformed socket), use the appropriate Flange Adaptor (6LB104 or 6LB106). Fix the flange adaptor to the unit using self-tapping screws. Drill a hole through the Flange Adaptor and connect the pipework. (6LB106 should not be used with AquaCell Eco).
8. In order to prevent silt from entering the tank, clogging inlet pipework and reducing storage capacity, it is recommended that the Domestic Silt Trap (6LB300) or the standard Silt Trap (6LB600) is installed prior to the inlet pipework – see page 22 for installation guidelines.
9. Wrap and overlap the geotextile covering the entire AquaCell structure, to protect the geomembrane.
10. Lay 100mm of coarse sand between the trench walls and the AquaCell units and compact.
11. Lay 100mm bed of coarse sand over the geotextile and compact. Backfill with suitable material. .
NB: A storage tank must be vented, and it is recommended that one vent pipe, 110mm in diameter is provided per 7,500 square metres of impermeable catchment area on a site, see page 22 for design.
